Overview
The CAP OPHWIS-010 is a set of four 10 lb cast iron plates, 40 pounds total, finished in black for standard barbell loading.
Cast iron is the traditional plate material, valued for its density and low cost compared to bumper or rubber-coated plates, though it is noisier when set down and can chip paint on a barbell over time. Four 10 lb plates gives two per side of a standard bar.
- Four 10 lb plates
- 40 lbs total
- Cast iron construction
- Black finish
Who it's for
Fits a lifter building out a plate collection at home who needs matched pairs for balanced loading. Less suited to anyone needing bumper plates for drops from height, since cast iron is not built to be dropped.
Pros and cons
- Set of four gives two matched pairs
- Cast iron holds weight precisely
- Standard sizing fits most barbells
- Not rated for dropping like bumper plates
- Bare cast iron is louder and can chip
Performance notes
Cast iron plates hold their weight rating precisely and stack tightly on a bar, the tradeoff being that dropping them on a hard floor can crack the plate or damage flooring, unlike rubber bumper plates built for that use.
